Using a number of search engine optimisation-driven subject lines, the latest campaign tries to get recipients to click on 'harmless' html attachments which launches an obfuscated Javascript attack that sends users to a variety of websites peddling everything from bogus CODECS to pharmacy.

One in particular, a standard advert for fake antivirus software, installs a back door - even if the browser is closed so by the time the html file has been clicked it is already too late.

The only defences against this sort of attack are either for it to be filtered at the gateway so it never reaches the user, or for the user to disable Javascript in their browser. Security software on the PC might catch the exploit.

Spam built around html is nothing new, but does seem to have become a hot technique in the last year or so with some spammers. A popular variant is the bogus 'Delivery Status Notification Failure', a sneaky way to get the attention of a user without arousing suspicion.

More recently still, the spammers started embedding the Javascript inside the html file (rather than as a simple file attachment), to spread the horrible Zeus banking Trojan.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
